Pre-screening during IVF can test the embryos for factors such as Down syndrome before the embryo transfer. PGT-A is a scientific approach that can improve pregnancy rates of IVF up to 70% and helps reducing miscarriage rates by less than 10%.

Down syndrome, a genetic condition presents growth challenges such as developmental delays, learning disabilities, cognitive impairment, general health issues such as heart problems or immune disorders. It is known to be a serendipitous event in pregnancy with little predisposing factors apart from maternal age. "PGT is a proven technology that can reduce chances of birth associated abnormalities during conception", said Dr Durga Rao, Medical Director, Oasis Fertility.

High and medium risk couples who have had a previous pregnancy with chromosomal abnormalities, women who have had repeated miscarriages, women who have experienced previously failed embryo implantation, couples diagnosed with unexplained infertility, women older than age 35 and couples who are going through unsuccessful fertility treatments can benefit from the PGT-A screening technology, added Dr. Durga Rao.
